我现在使用docker compose来启动Dgraph，但它总是无法启动。docker-compose.yml的内容如下：
# This Docker Compose file can be used to quickly bootup Dgraph Zero
# and Alpha in different Docker containers.
# It mounts /tmp/data on the host machine to /dgraph within the
# container. You can change /tmp/data to a more appropriate location.
# Run `docker-compose up` to start Dgraph.
version: "3.2"
services:
zero:

volumes:
- /data/nlp/dgraph/data-volume:/dgraph
ports:

ratel:

ports:

command: dgraph-ratel
"与alpha的连接丢失：7080。错误：rpc错误：code=未知desc=尚未设置节点"总是出现在docker合成之后。
我花了三天时间换了三台机器，但都以失败告终。问题出在哪里？请帮我

请帮我找到问题，非常感谢
不确定我是否可以在SO上发布链接(如果这是违规行为，请随时删除(，但OP提出了这个确切的问题，并在这里回答了这个问题：
https://discuss.dgraph.io/t/dgraph-always-showsconnection-lost-with-alpha-7080-error/8392
我会从他们的文档中复制dgraph docker文件：https://dgraph.io/downloads
下载后使用docker而不是docker composehttps://dgraph.io/docs/tutorial-1/将其连接到D图。。祝你今天过得愉快！！
